Best Gas Credit Card for DoorDash, Grubhub, and Instacart Drivers

15 hours a week (part-time, $175 / month gas): Citi Custom Cash. Returns $120 a year at 5 percent inside the cap. No friction. The Wells Fargo Autograph at 3x returns $72 a year at this spend, much lower. PenFed Platinum returns $102, also lower.

25 hours a week ($280 / month gas): Custom Cash still wins. Returns $192 a year. PenFed returns $143; Autograph returns $108. The Custom Cash 5 percent cap is not yet binding.

35 hours a week ($420 / month gas): Custom Cash still wins. Returns about $251 a year inside the cap. PenFed returns $214; Autograph returns $151. The Custom Cash cap is approaching but not yet binding.

45 hours a week ($560 / month gas): PenFed Platinum overtakes. Returns about $286 a year (5x on $6,720 annual spend at ~4.25 percent effective). Custom Cash at this level returns $312 (still slightly higher because the cap binds at the $500 cycle, returning $300 at 5 percent plus $7 at 1 percent), but at this spend level PenFed has the structural runway. At 50+ hours a week, PenFed pulls ahead.

DoorDash, Grubhub, Instacart, and Uber Eats drivers all receive 1099-NEC forms reporting earnings. Gas is one of several deductible business expenses. Drivers can elect the IRS standard mileage rate (which covers all vehicle costs including gas) or actual expenses (where gas is a separate line). Most part-time and full-time delivery drivers find the standard mileage rate produces a larger deduction than actual expenses, particularly for newer vehicles where depreciation is substantial.

Credit-card cash back on gas is not taxable income. Under actual-expenses accounting, the cash back reduces the deductible gas amount (gross gas minus cash back equals deductible gas). Under standard-mileage accounting, the cash back simply reduces your out-of-pocket cost without affecting the deduction.

Mileage tracking matters more than gas tracking for most delivery drivers, because the deduction is mileage-based. Apps like Stride, Everlance, and MileIQ track miles automatically. Without good mileage records, drivers default to actual expenses, which usually produces a smaller deduction. Keep both gas receipts and mileage logs if you have the discipline; use standard mileage if you do not.

Delivery drivers fill frequently, which makes app-based stacking more valuable than for low-mileage commuters. Upside offers 5 to 25 cents per gallon cash back at participating stations when you check in through the app and use a linked debit or credit card. GasBuddy Premium offers up to 25 cents per gallon off through the Pay with GasBuddy program.

The stack: use a 5 percent gas card (Custom Cash) at the pump, then claim the Upside reward separately through the app. At $3.50 per gallon and a 14-gallon fill, the card returns about $2.45 (5 percent) and Upside returns roughly $1.40 (10 cents per gallon). Total $3.85 per fill, effectively 7.85 percent of the purchase. Across a $420-a-month gas budget, the stack returns about $396 a year vs $252 from the card alone. The roughly 50 percent return uplift makes the per-fill app check-in worthwhile for high-frequency drivers.

The catch: each app has setup overhead (linking a card, enabling location services, checking in at each fill). For drivers who file 15-second app check-ins as friction, the marginal $100 to $150 a year may not be worth the operational tax. For high-volume drivers, the per-fill effort is rounded into the workflow.
